Abstract (en)
[origin: EP3753696A1] In the method for making a waterproof floor slab element (24), fresh concrete mix is poured into a casting mold (10), which has a mold surface (12) that forms the shape of the top surface (30) of the floor slab element, the concrete mix is allowed to harden in the mold to form a floor slab element, and the floor slab element is removed from the mold. A surface structure improving the adhesion of the waterproofing material is arranged on the top surface of the floor slab element, and a waterproofing layer is formed on the top surface. The adhesion-enhancing surface structure is formed by installing a porous mold fabric on the mold surface before pouring the concrete, whereby a surface structure corresponding to the surface shape of the mold fabric is copied onto the top surface.
